SPECIFICATION forming part ofvLetters Patent No. 322,548, dated July 21,1885.

Application filed February 24, 1883. (No model.)

Zo @ZZ whom it may concern:

Be it known that I, JOHN LUoAs, a citizen of the United States, residingat Hastings, in the county of Dakota and State of Minnesota, haveinvented a new and useful Wheat, Oat, and Oockle Separator, of which thefollowing is a specification.

This invention relates to wheat, oat, and cockle separators, and itconsists in the novel construction and combination of parts, which willbe first fully described, and then pointed out in the claims.

In the drawings, Figure I is a perspective, and Fig. 2 a verticallongitudinal section, of my machine. Fig. 3 is a detail view of one ofthe slides. Fig. 4 is a detail view of the elevator. Fig. 5 is a detailview of the end spout, Fig. 6 is a detail view of the lower supplementalsieve. Fig. 7 is a detached sectional View of the main sieve and theendless slotted apron. Fig. S is a detail perspective View of the hopperand main sieve. Fig. 9 is a detail view of the slide-sections. Fig. 10is a detail view of the upper supplemental sieve. Fig. Il is a detailview of the side spout, all of which will be described.

The supporting-frame of my machine is formed of the inclined sideboards, AA, supported by their upper forward ends by legs B, which areslotted vertically at b, and secured to the side frames by set-screwsb', passed through said slots, so the side boards can be adjustedvertically to Vary their inclination. Legs C C support the lower end oftheiside boards, and an end board, C', extends between and-connects saidlegs C. The side boards are' provided in their upper ends withbearingslots D, and in their lower ends with slots D', and the mainsieve E is secured between said side boards, below the slots DD', and atan inoline, as shown. The hopper F is arranged at the upper end of themachine and provided with an agitating-roller, f, having an end pulley,f', and with a discharge-opening, F'. A tilting board, G, is pivoted atits forward edge in advance of the opening F', and eX- tended under andbeyond said opening, with its rear edge over the upper end of the mainsieve, as shown. This board G is provided at or near its tilting edgewith a springarm, G', which extends alongside of the hopper and engagesthe teeth of a rack, F2, so that the tilting board may be held at anydesired inclination for the purpose of regulating the outmental77 sieve.

flow of the grain. The endlessl apron H is provided with cross-slats H',and is supported on rollers I I'. The roller I has its trunnionssupported in slots D, and provided on one end with a pulley, t', and onits other end with a hand-crank, i', and a pulley, t2. The pulley ft2 isgeared by belt '3 with pulley f', and thus operates the agitator f, aswill be understood. The roller I' has its trunnions projected throughslots D' and journaled in plates J, which are adj ustably secured to theside boards, A, by set-screws J', passed through slots j, so that theapron may be tightened when desired. This belt is moved in the directionindicated by the arrow in Figs. I and 2, and feeds the grain down on themain sieve. A sieve, K, is arranged below the upper end of the mainsieve and extended slightly below the middle part of said main si'eve,as shown. I preferably pivot this sieve midway its ends, so it may beadjusted to any desired angle, and it may be held at the desired angleby fitting it to lbind between the side boards, A, or by set-screws, orother similar expedients, as desired. I also prefer to form this sievewith tw`o screens, one above the other, as.shown most clearly in Fig. 2.The spout L is arranged at the side of the machine, below the sideboards, A, and slightly nearer the lower than the upper end' of themachine. Inclined grooves M' are formed in the inner sides of the boardsA A, between the spout and the sieves K, and extend downwardv below therear side of the spout and upward to a point about midway the ends ofthe sieve K. A cutoif board, M, is supported and movable in thesegrooves above the spout L, and between the latter and the sieve K. Byadjusting this cut-off to the position shown in Fig. 3 it will out offthe grain screened by the lower half of sieve K from spout L, anddeliver sameinto the end spout, presently described. By adjusting thiscut-off M in its grooves, the grain screened bythe lower part of sieve Kmay be delivered into either the side or end spout, asY desired. Thesieve K, I denominate, for purposes of reference,theupper supplemental77sieve, and the sieve N, the "lower supple- This latter sieve is arrangedbelow the sieve K, and has its lower end projected slightly over theside spout and its upper end extended to a line below the forward end ofsieve K. This sieve is also preferably pivoted midway its ends forpurposes of ad- ICO justment, and may be held in any desired position ina manner similar to that described with reference to the sieve K. Anarrow board, O, is arranged at an incline between the the slidingcut-offs P P. The upper groove,

P', is extended nearly to the lower end of the upper vsupplementalsieve, and either or both the cut-oifs P may be adjusted in theirgrooves to throw the screenings from the lower part of the main sieveover the end board or into the end spout. This endV spout, Q, dischargesthrough an opening, C2, in end board, (Y, and thence through an opening,R', into the case of the elevator R. This elevator is arranged at thedischarge end of the machine, and is provided with an endlesscarrying-belt, R, supported on rollers R3 R3, the upper one of which isprovided with a pulley geared by beltS with pulley t' on roller I. Thegrain, tailings, Svc., delivered through opening R is taken up by theelevator and deposited by spout It* onto the apron, by which itiscarried upward and redelivered onto the main sieve. The elevator may besupported at its lower end by a foot-board, T, which rests on the iioorand may be screwed to the end board, C. This foot-board holds theelevator away from the end board, C', andits upper end is inclined so asto throw the dbris, tc., delivered over the end of the machine toopposite sides. The upper end of the elevator is braced by vthestay-rods U U, as shown. The cut-offs P P and M, it will be understood,may be held at any point of adjustment by fitting them sut'- cientlytight in the grooves P M to hold them from any movement except whenpositively actuated, as will be seen.

In operation motion is given by crank t', and the grain passes out ofthe hopper and is carried by apron H down over the sieve E.

The unhulled grain, dbris, te., which fails 4to pass through sieve E isdeposited at the end ofthe machine onto the floor or ground, where itmay be collected and disposed of as desirable., The grain passed throughthe upper part of sieve E' passes onto sieve K, and is screened throughthe same or passes off its lower end onto cut-off M, and thence into theend spout. By adjusting the said cut-off downward the grain screened bythe lower part of the sieve K may be delivered into the end spout, orthe said board M may be set farther downward in its grooves so it willcatch but a small quantity of grain screened by sieve K, the major partfalling onto sieve N, and thence into the side spout, as will be seen.The grain passes down sieve N, by which any fine dust or dirt isseparated from it, and into the side spout, out of which it flows inproper condition for bagging. The main sieve is coarser than the uppersupplemental sieve, and the latter is coarser than the lowersupplemental sieve, so the screened matter is reduced in quantity as itflows through the machine. The matter which is thrown off from the sieveE is cast out of the machine, and the other matter, except that whichhas been properly separated, is redelivered into the main sieve, andagain run through the machine.

In starting the machine the tilting board is adjusted to permit a vfullfeeding, and as the elevator begins to deliver the grain onto the apronthe feed from the hopper is limited according to the quantity brought upby the elevator, in order that the quantity of stuff running through themachine may not exceed its capacity.

The supplemental sieves may be adjusted on their pivots to variousangles, according to the quantity of grain passing through the machine.

Having thus described my invention, what' I claim, and desire to secureby Letters Patent, is-

l. In a grain separator, the combination, with the main sieve and anendlesscarrying apron, of an elevator arranged at the rear or dischargeend ofthe sieve and adapted to receive the discharge of the machine andelevate such discharge onto the endless belt and operating mechanism,substantially as set forth.

.2. The combination, in a grain-separator, of the stationary inclinedsieve, the endless apron having cross-slats and moving down on the saidsieve close thereto, and an elevator arranged at the rear' end of themachine and adapted to receive the mixed grain and tailings and elevateand deliver the same onto the lower end ofthe slatted apron, wherebythey are redelivered onto the inclined screen, substantially as setforth.

3. In a grain-separator, substantially as described and shown, thecombination of the sieve E, the slatted apron, the hopper, the elevatorarranged at the end of the machine and adapted to receive the mixedgrain and tailings screened by the lower part of the sieve E, anddeliver the same onto the slatted apron, and means whereby the dischargefrom the hopper may be regulated, substantially as described, and forthe purposes specified.

4. In a grain-separator, the combination of the main sieve, the sieve K,the cut-offs P, the cut-oft' M, and the side and end spouts,substantially as set forth.

5. The combination of the main sieve, the sieves K and N, the spouts Land Q, and the cut-offs M and P, substantially as set forth.

6. The combination, with the main seive, of the cut-offs P P, arrangedbelow the lower end of the main sieve and adjustable one upon the other,substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
